1N941 thru 1N946B-1
11.7 Volt Temperature Compensated Zener
Reference Diodes
DESCRIPTION
The popular 1N941 thru 1N946B series of Zero-TC Reference Diodes
provides a selection of 11.7 V nominal voltages and temperature
coefficients to as low as 0.0002%/oC for minimal voltage change with
temperature when operated at 7.5 mA. These glass axial-leaded DO-7
reference diodes are also available in JAN, JANTX, and JANTXV military
qualifications. Microsemi also offers numerous other Zener Reference
Diode products for a variety of other voltages from 6.2 V to 200 V.
APPEARANCE
DO-7
(DO-204AA)
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
• JEDEC registered 1N941 thru 1N946B series
• Standard reference voltage of 11.7 V +/- 5% with
tighter tolerances also available
• 1N941B, 942B, 943B, 944B, 945B also have military
qualification to MIL-PRF-19500/157 up to the
JANTXV level by adding JAN, JANTX, or JANTXV
prefixes to part numbers as well as “-1” suffix, e.g.
JANTX1N944B-1, etc.
• Internal metallurgical bonds
• JANS Equivalent available via SCD
• Radiation Hardened devices available by changing
“1N” prefix to “RH”, e.g. RH944B, RH945B, etc.
Also consult factory for “RH” data sheet brochure
APPLICATIONS / BENEFITS
• Provides minimal voltage changes over a broad
temperature range
• For instrumentation and other circuit designs
requiring a stable voltage reference
• Maximum temperature coefficient selections
available from 0.01%/ºC to 0.0002%/ºC
• Tight reference voltage tolerances available at 11.7
V nominal values by adding the tolerance 1%, 2%,
3%, etc. after the part number for further
identification e.g. 1N944B-2%, 1N945A-1%,
1N944B-1-1%, etc.
• Flexible axial-lead mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method 1020
MAXIMUM RATINGS
• Operating & StorageTemperature: -65oC to +175oC
• DC Power Dissipation: 500 mW @ TL = 25oC and
maximum current IZM of 39 mA. NOTE: For optimum
voltage-temperature stability, IZ = 7.5 mA (less than
95 mW in dissipated power)
• Solder temperatures: 260 oC for 10 s (maximum)
MECHANICAL AND PACKAGING
• CASE: Hermetically sealed glass case with DO-7
(DO-204AA) package
• TERMINALS: Tin-lead plated and solderable per
MIL-STD-750, Method 2026
• MARKING: Part number and cathode band
• POLARITY: Reference diode to be operated with
the banded end positive with respect to the
opposite end
• TAPE & REEL option: Standard per EIA-296 (add
“TR” suffix to part number)
• WEIGHT: 0.2 grams.
• See package dimensions on last page
